A 2011 study by Harvard University analysized the urine of seventy-five people for BPA. Each participant ate a 12-ounce serving of either fresh or canned soup for five days in a row. They were advised not to otherwise alter their regular eating habits. After a two-day break, the groups switched and ate the opposite type of soup. The study showed the canned soup eaters had 1,221 per cent higher levels of BPA in their urine than those who ate the fresh soup.5 Of other concern, a 2012 study out of New York, the first study of its kind to test for BPS, found 81% of the urine samples tested contained BPS (Bisphenol S)* in quantities just slightly below those of BPA.6 – See more at: http://www.inspirationgreen.com/bpa-lined-cans.html#sthash.gVnnTPQJ.dpuf
